 ABSTRACT

A field experiment was carried out during rabi season of 2016-17 to evaluate the effect of different levels of PSB and KSB on growth and yield of maize. The experimental results revealed that application of 45 kg P2O5/ha + PSB seed inoculation + PSB soil application promoted growth parameters viz., plant height, dry matter per plant, functional leaves per plant, number of internodes per plant and yield attributes viz.,cob length, cob girth, number of grain rows per cob, 100 grain weight, grain weight per cob, shelling percentage and ultimately gave higher grain yield (3452 kg/ha) and straw yield (5300 kg/ha) with higher net return (₹ 40018 ha) and B:C ratio (2.11) over the control. Application of 45 kg K2O/ha + KSB seed inoculation + KSB soil application enhanced growth parameters viz., plant height, dry matter per plant, functional leaves per plant, number of internodes per plant and yield attributes viz.,cob length, cob girth, number of grain rows per cob, 100 grain weight, grain weight per cob, shelling percentage and resultantly gave higher grain and straw yield of 3476 and 5295 kg/ha, respectively along with higher net return (₹ 40695/ha) and B:C ratio (2.14) over the control.It could be concluded that seed inoculation and soil application of PSB and KSB enhanced grain yield with higher net return and saving of 25% fertilizer dose of phosphorus and potash.

Key words:Popcorn, (Zea mays L. Var. Everta), Phosphate solubilizing bacteria, Potash solubilizing bacteria.
